1. COOLING OPERATION
1-1 COOLING CAPACITY CONTROL
A sensor (room temperature thermistor) built in the indoor unit body will usually perceive
difference or variation between a set temperature and present room temperature, and
controls the operation speed of the compressor.
* If the room temperature is
2°C higher than a set temperature, the compressor operation
speed will attain to maximum performance.

( Table 1 : Compressor speed range )
When the compressor operates for 30 minutes continuously at over the maximum speed ,
the maximum speed is changed from Maximum speed to Maximum speed .

* When the room temperature is between +2°C to -2.5°C of the setting temperature,
the compressor speed is controlled within the range shown in Table1.
However, the maximum speed is limited in the range shown in Figure 1 based on the
fan speed mode and the outdoor temperature.
* If the room temperature is 2.5°C lower than a set temperature, the compressor will be
stopped.
